They aren't giving you a new account or anything just issuing you a new card on your existing account with them.
Likewise the card issuer most probably reserves the right to change the affiliate program as well.
Costco switching from Amex to Citi Visa is definitely a change. Don't think the Costco Amex was issued by Citi bank. Had to go directly to the Amex site to pay the bills. Have other Amex cards issued by other banks and always go to the bank that issued it to pay those bills. So don't know why Costco can do it but Virgin America couldn't as people seem to be implying.
